Matter is made of atoms, vast collections of atoms.
Differences in matter are due to different amounts of protons and neutrons in the atom. Elements are distinguished by the number of protons, whereas isotopes (same element but different mass) are determined by the number of neutrons.
Most of the universe consists of empty space. However, the most common "visible" element is hydrogen.
Hydrogen is the most abundant gas in the universe
Stars make up most visible matter. By far most visible light is given off by hydrogen fusing into helium
Hydrogen gas.

Hydrogen is the most abundant element in the universe, making up around 3/4th of all matter. When it comes to Earth's richest element, it differs from that of the universe. In Earth's crust, oxygen gas makes up a total of [around] 47% of the Earth's mass, making it the most disseminated element on Earth.
The mass number is the sum of the protons and neutrons in the atomic nucleus.
Of all the baryonic matter, aluminium makes up about 0.005%. Considering that ordinary baryonic matter makes up about 4.9% of the universe, that would make aluminium constitute about 0.049 x 0.00005 = 0.000000245% of the mass of the universe.
In terms of the total mass of the universe, it is single elements.
Plasma. It makes up more than 99% of visible matter in the universe, and most of the invisible matter.
The most abundant element in the universe is hydrogen, which makes up about three-quarters of all matter! Helium makes up most of the remaining 25%
Depends what you mean by "a lot." The gravitational effect of dark matter -- whatever the stuff happens to be -- is about six times greater than that of all the visible matter in our Universe.
Hydrogen is the most common element in our galaxy.
matter is anything that occupies space and has mass.
The Universe is everything . So, Aluminium makes up part of the universe: a tiny fraction of it.
matter has mass and takes up space.matter
All matter in the universe.
All matter has mass. People, buildings, rocks, water, the air, the sun, and everything else that makes up the physical universe (except for energy) is made up of matter. Mass is defined by its resistance to change in motion, commonly called inertia.
Atoms make up most matter around us. In the Universe in general, it seems that atoms make up about 4% of the mass of the Universe. The remainder of the Universe mass is dark matter and dark energy - both of unknown composition.
